Meteo Coimbra in agosto

Two expectations need correcting for an August visit. The giant waves Nazare is famous for are a winter phenomenon - November is the peak, and October to March the season - so in August the surf here is ordinary. And this is the Atlantic, not the Mediterranean: regulars describe the beach as often windy even in high summer and the water as cold whatever the air is doing, with nights around 15 to 17C and a light jumper wanted in the evening. What August does give is the town at its liveliest and the clifftop funicular view without the winter crowds of wave-watchers. The record: 25.7C days, 17.1C nights, half a precipitation day, 12.2 hours of sun, a 17.2C sea and a 23 kph wind.

Forum posters describe November in Coimbra as genuinely variable - one visitor's four-day stay brought rain almost every day, while posters more broadly describe a typical visit needing only a shower or two in the morning, with some years bringing lots of warm weather punctuated by the odd rainy day and chilly evenings. Posters consistently recommend packing a raincoat and umbrella, and good walking shoes given how slippery Coimbra's cobbled streets get when wet. Posters are direct that November counts among Portugal's more difficult, rain-prone months overall, but also one of the least touristic alongside January, meaning shorter lines and quieter sightseeing at Coimbra's university and historic sites. Posters generally rate November as genuinely rain-prone but rewarding for a Coimbra visit, with low crowds a real upside of the wetter shoulder season.

Forum posters describe May in central Portugal as edging toward summer, with typical daytime temperatures in the 20-23C range cooling to around 13C overnight. Opinions on packing split a little: some posters say shorts and sandals are enough given how close the weather is to summer, while others recommend bringing a light jacket since rain remains a real possibility this early in the season. For Coimbra specifically - a university town known for its historic architecture along the Mondego river - posters describe it as a pleasant, walkable size for a day or two, with a genuinely hot day always possible even in May, per one visitor who ducked into a shopping mall's food court specifically to escape unexpected heat.
